CAR-DUMPING MECHANISM.

To all whom itQ-mag concern:

Be it known that I, GEORGE H. Human, of Cleveland, in the county of Cuyahoga and have invented certain new and useful Improvements in Car-Dumping Mechanism; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains t9 make and .use the same.

This invention relates to improvements incar dumping mechanism, the object of the invention being to provide simple and efiicient means for raising, lowering and tilting a cradle carrying a car to be dumped, and to economize time and power in efiecting such erations. y

Wit this object in view, the invention consists in certain novel features of construction and combinations of parts as hereinafter'set forth and pointed out in the claims.

The accompanying drawing is a diagrammatical view of an apparatus embodying my improvements 1 represents a cradle comprising a platform 2 onto which a car to be dumped will be run, and a vertical portion 3,- he latter being provided with rollers such as indicated at 4, to run on upright guides 5, and said cradle is also provided with rollers such as indicated at 6, to run on upright guides 7. Each guide is made with an outwardly projecting portion which may be curved as'sh'own at 8, and at the end of this curved upper part of the guide, a curved stop 9 is provided. The guide 7 is provided at its upper portion with an inwardly or rearwardly pro- 11 for the upper part of said guide 7 The guides 5-7 are secured to and carried by a Specification of Letters Patent. Application filed June 2. 1913. Serial No. 771,292.

' connected with the.

'ablv through the horizontal beam 12 which is vertically movable in any suitable framework-screws 13 being provided for adjusting said beam vertically, and these screws may be operated through gears let-s15 from any convenient source of power connected with the shaft 16 to which the gear 15 is secured, An apron tended to'receive material dumped from a car and deliver it through a suitable chute or conveyer to the hold of a boat.

To one side of the cradle, lifting cables, such as indicated at- 19, are attached, each extending upwardly from its connection with the cradle andt Patented Jan. 13, 1e14 passing over pulleys 20-21 vlocated in a plane above that of the highest point of adustment of the beam 12. From 21, each lifting cable extends downwardly and 1S wound on a drum 22, to which power may be applied and the operation of which may be controlled by any suitable means.

A cable 23 is connected with the cradle preferably at a point approximately concentric with roller 4, and from such connection, eachcable 23 extends upwardly and, after passing over pulleys 24--25 located above the plane of that to which the beam 12 is adjustable, the depending end of each cable 23 is provided with a counterweight 25. The counterweight 25 is such as will be sufiicient to raise the pivot side of the cradle,- while the other side of the cradle will be hoisted by the cable 19.

Clamp-bars 26 for clamping a car 27 to the cradle while the latter is being tilted duringthe dumping operation) are pivotally cradle, preferably through the medium of clam s 28, said clamping bars and clamps an means for controlling the operation of the latter to engage a car, being well known in the art. cable 29 is connected with the cradle (prefermedium of each clamp 8) and, after passing over the clamp bar 26 an under a pulley 30 at the free end of the latter, each cable 29 extends upwardly and over pulleys 31-32, the free depending end of each terweight 33.

When the drum 22 is rotated in one dir tion, the cradle will beraised and partial the pulley cable 29 being provided with a own 0 tilted by the rollers 6 running on the cam portions 11 of'guides 7 ,-the cable 19 serving to hoist one side of the cradle and the weighted cables 23 operating to raise the other side,--until the rollers 4 reach the pivotal supports afforded by the stops 9 at the upper end of guides 5, and then, by continuing to hoist by means of'the drum 22 and cable 19, the tilting of the cradlewill' be completed and the clamp bars caused to extend transversely across the top of the car. It will be remembered that the coin ter weights will be heavier than the comhin weight of the cradle and car. It will therefore be necessary to provide 'a cable 34, which is wound on the drum 22 in an opposite direction to the windin 0 the cable 19 and after passing upward y and over a able pulley 35 located in av plane above that of the highest point reached by the weight 25, said cable 34'is extended downwardly and attached to said weight 25. From this construction, it will be an empty car are being returned, the coun tel-weight 25 (which is noW heavier than the combined weight of the cradle and car) will be lifted, thus allowing the car to descend..
